Every 25 minutes, a baby is born addicted to opiates, according to the National Institute of Drug Abuse (NIDA).

The withdrawals these babies have are heartbreaking, and their condition has a name: neonatal abstinence syndrome (NAS). The cause of NAS is a mother who abuses drugs while pregnant, passing that addiction down to her child.

Za’lani Porter

Za’lani's mom, Raeven, had been addicted to drugs for years. According to Fox 29 News, when Raeven was 5 months pregnant, she overdosed.

Though Za'lani wasn't born addicted to heroin, since Raeven had been on life support at the time of her birth, she was born addicted to the Phenobarbital and the Benzodiazepine used to control her mother's seizures.

Jordynn

When Jordynn was born dead, doctors had to revive her. A Kentucky-based heroin support group shared Jordynn's story on YouTube, explaining she was born 9 weeks early and addicted to heroin. She spent her first 46 days in the NCIU.

Jacey Frazier

Like many other cases, Jacey's mother, Jennifer Frazier, was on methadone during her pregnancy to combat her prescription painkiller addiction.

Jacey had uncontrollable shaking when she was born, a sign she was suffering from the withdrawal of methadone.

According to NBC News, she mistakenly gave Jacey a “lethal does” victim of a lethal dose of methadone to Jacey when she was six months old, resulting in her untimely death.

Here's what a baby typically goes through when they're born addicted to drugs:

A new study published in JAMA Pediatrics on Sept. 26 found that rates of NAS have doubled since 2009.

Lead study author Dr. Joshua Brown, a pharmacy researcher at the University of Kentucky in Lexington, told Fox News a reason behind some of the surge in NAS among babies is due to strict prescription drug policies:

“The drug policies of the early 2000's were effective in reducing supply — we have seen a decrease in methamphetamine abuse and there have been reductions in some aspects of prescription drug abuse. However, the indirect results, mainly the increase in heroin abuse, were likely not anticipated and we are just starting to see these.”

In 2014, the NIDA estimated that 1.9 million people in the U.S. were addicted to prescription pain relievers and roughly 586,000 had a substance use disorder involving heroin.

To make matters worse, the Centers for Disease Control and Prevention says 45 percent of people who used heroin were also addicted to prescription opioid painkillers.

Though federal law has called on states to contact social services when babies are born with a drug addiction, a recent Reuters investigation found that many aren't complying, putting countless infants at risk.
